In addition to skewing disease rates as a result of the misdiagnosis on non-cancerous lesions, there also is evidence that the sites and distributions of lesions diagnosed as melanoma many times do not correspond to exposure to sunlight being the primary cause.
I believe this to be dangerous advice, given on the basis of one small study. If you want facts, try this:
Skin Cancer Facts & Statistics - SkinCancer.org
The vast majority of melanomas are caused by the sun. In fact, one UK study found that about 86 percent of melanomas can be attributed to exposure to ultraviolet (UV) radiation from the sun.
Melanoma is one of only three cancers with an increasing mortality rate for men, along with liver cancer and esophageal cancer.
Cover up, use sun block and minimize your sun exposure. Dermatologists think you should use sun block for your walk between house and car. Take vitamin D if determined to be a good idea by your doctor. Low blood levels of vitamin D are indicative of fracture risk and many other ailments and health risks.
